HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 749,662, dated January 12, 1904 Application filed June 25, 1903. Serial No. 163,058. (No model.)

To all whom it may concern Be it known that I, J osnrn O. Dnivraoma citizen of the United States, and a resident of Roanoke, in the county of Roanoke and State of Virginia, have made certain new and useful Improvements in Hay-Presses, of Which the following is a specification.

My invention is an improvement in balingpresses especially designed for baling hay, but which may be used for other material when desired; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

. In the drawings, Figure 1 is a side elevation, partly in section, of a press embodying my invention. Fig. 2 is a longitudinal section of a portion of the press. Fig. 3 is a longitudinal section of a portion of the press. Fig. 4 is a plan view, partly in section, of a portion of the press. Fig. 5 is a detail perspective view showing the base-frame, the gear-frame, and parts connected therewith. Fig. 6 is a detail perspective view of the base or bed frame and the gear-frame. Fig. 7 is a detail cross-sectional View on about line 7 7 of Fig. 4. Fig. 8 is a detail perspective view of the lockinglever. Fig. 9 is a cross-sectional view on about line 9 9 of Fig. 4:. Fig. 10 shows a.

somewhat different construction bale-box.

In carrying out my invention I employ the bale-box A, together with suitable framing for the press, which bale-box and framing may be in general respects and except as hereinafter described of ordinary construction.

At A a suitable feed-opening is provided, through which the hay may be introduced, and the head-block B may be suitably secured in the outer end of the bale-box to form the backing in pressing the first bale, each bale thereafter forming the backing for the following bale, as is usual in baling-presses. I also provide in the bottom of the press an opening A located at about the end of the rearward travel of the plunger and adapted to permit any hay that may be drawn back with theplunger to escape, and so prevent any clogging of the press at the rear side of the plunger. The plunger C is fitted to the bale-box, has rollers O to ease its travel back and forth, and has connected with it the rack-bars D, of which I preferably employ two, as shown. In connecting the rack-bars D with the plunger I prefer to efltect it by means of the cross-rod D, to

which the ends of the bars D are connected,

such cross rod D extending through the plunger from side to side and projecting beyond the opposite sides thereof and entering guide-slots d in the opposite sides of the balebox. By this means I guide the plunger back and forth and prevent the same from lifting and so binding within the bale-box in the operation of the invention. The rack-bars D extend rearwardly from the plunger and slide back and forth in guides E supported in what for convenience of reference I term the bed-frame E, the latter being preferably bolted or otherwise secured rigidly to the frame of the press and affording a guide-support for the rack-bars D and a means to facilitate the hinging of the front end of the gear-frame F, which will be presently described. Manifestly in the broad features of my invention I do not desire tobe limited to the specific construction of the bedframe; but the construction shown is preferred, as it affords an elevated guide-support for the rack-bars D of the plunger and also facilitates the hinge connection of the gearframe, as before suggested. In securing the bed-frame E, I prefer to provide bolts E, ex

tended upwardly from the base of the pressframe through the bed-frame and projecting at their ends above the bed-frame to form dowel devices between the bed-frame and the hinged gear-frame, by which to steady the gear-frame when lowered to position for use and to preings for the shaft I, on which are secured the This gear-frame has bear bale-box and press the bale.

gear-wheels I, meshing with the rack-bars D,

and the ratchet-wheel I for engagement by the operating pawl J and the detent-pawl K. The operating-pawl J is carried by the pawl-lever J and engages with the ratchetwheel I and operates the same in the proper direction to cause the wheels I, meshing with the rack-bars D, to force the plunger into the The detent-pawl K is suitably pivoted, preferably to the bedframe, and engages the ratchet-wheel and operates as a detent to prevent the reverse movement of the shaft I as the pawl-lever J is returning from its operative stroke. This pawllever J may be made sufliciently long to be grasped by the hand and be worked directly by the operator where excessive force may not be desired or necessary; but I prefer in practice to provide the handle-lever L, which is pivoted at its lower end to bracket L, connected with the press, and is connected by links L with the pawl-lever, so the latter may be operated by the handle-lever, whereby I am enabled to secure the double leverage, and consequently great power, in the operation of the press. When the devices have been operated to force the plunger to the extreme of its stroke and the bale has been pressed, it is desired to quickly return the plunger. For this purpose the gear-frame may be adjusted away from the bed-frame to move its gear-wheels I out of mesh with the rack-bars D, so the spring Gr can quickly retract the plunger. I provide means for such purpose, and I also provide means for locking the gear-frame in position, with its wheels I meshing with the rack-bars D, and for convenience I combine the locking devices and the releasing devices, so the gear-frame can be quickly unlocked and then shifted to adjust its gears out of mesh with the rack-bars. In the construction shown this is accomplished by means of the locking and shifting lever M, which is pivoted at its lower end at M, has a cross-bar M which may be adjusted above the swinging end of the gear-frame to lock the said frame in position for use, and said lever M is also provided with a crank-arm or projection M which engages the swinging end of the gear-frame G after the cross-bar M has been swung off of said hinged end and lifts the hinged end of the gear-frame to such extent as to move the gear-wheels I out of mesh with the rack-bars D, so the latter can slide rearwardly in the readjustment of the plunger by the returning-spring G. To facilitate the sliding of the rack-bars D in both directions, I prefer to mount them in guides E in the form of grooved platessecured on the bedframe E, as shown in the drawings.

While in Figs. l and 2 of the drawings I have shown the bale-box as constructed of wood in the usual manner, it is manifest where desired this bale-box may be made of sheet metal, as illustrated in Fig. 10.

In the operation of my invention it will be understood that when the plunger has been advanced to the end of its stroke, which it has nearly reached in Fig. 1, the gear-frame will be locked on the bed-frame by the lever M. If now' it be desired to release the gear devices, so the plunger may be retracted by the springG, the lever M will be moved from the position shown in Fig. 1 to that shown in Fig. 2, which will release the cross-bar M from engagement with the gear-frame and will cause the crank-arm or proj ectionM engaging in the notches e, to lift the gear-frame to the position shown in said Fig. 2, so the gear-wheels I will be lifted out of mesh with the rack-bars D and the spring G will quickly return the plunger. Hay may now be supplied through the opening A, the lever M be moved from the position shown in Fig. 2 to that shown in Fig. 1, permitting the gear-wheels I to drop by gravity into mesh with the rack-bars D and the cross-bar M being adjusted to bear upon the gear-frame and lock the same in position until the plunger has again been advanced to the end of its stroke and it is desired to return the same for a new operation.
